Sculk Hoard implements a new end-game era to your game that once activated, will force you to fight against the newly awaked ancient sculk hoard in order to survive. This ancient enemy seeks to infect and consume the world in it's entirety.
Given how the darkness effect is more prevalent from nodes, and how more dangerous fighting the Horde becomes with the Darkness Effect, I think a potion of Darkness Resistance should exist to ease on taking out nodes.
My take on a Potion of Darkness Resistance:
Needs a Crying Soul as the brewing ingredient, base potion lasts for a minute.
Can be upgraded with redstone to give 3 minutes of resistance.
